Comments and Curiosities

Found in three locations along the Maroni River Which borders Suriname, in Maripasoula, north to Papaïchton, and then twice as far again north along the banks of the river, virtually half in the water as the photos below displays.

In Ecuador it's found at elevations between sea level and 230 m. It competes succesfully in seasonally flooded forests, and have been found in areas flooded from 30-240 days per year.

Fruits from the tree are consumed by fish, and could prove useful in supplying fodder for fish.
